Here are 5 of the more popular software programs that can be used to help ensure that a web site meets the standards for accessibility. It is important to note that these automated programs can be extremely useful in quickly identifying a wide range--but not all--of the barriers to accessibility. Like virtually any set of complex decision rules applied automatically, they can result in false positives and false negatives.
A-Prompt Web Accessibility Verifier
A-Prompt (which stands for Accessibility Prompt) is "a software tool designed to improve the usability of HTML documents by evaluating Web pages for accessibility barriers and then providing developers with a fast and easy way to make the necessary repairs." A-Prompt's software reflects the accessibility guidelines developed by the Web Access Initiative (WAI) of the World Wide Web Consortium.(W3C). It is a joint effort of the University of Toronto's Adaptive Technology Resource Centre and the University of Wisconsin's Trace Research & Development Center.
InFocus is a software program developed by SSV Technologies "for making Web sites and applications accessible to people with disabilities and compliant with Section 508 requirements. InFocus allows developers to check their pages for accessibility errors, and then automatically fixes any violations."
LIFT is software that reflects both Section 508 and W3C/WCAG guidelines. There are versions specific to the Mac OS, to Macromedia Dreamweaver, to Microsoft FrontPage, and other specific systems.
RAMP is a software program developed by Deque Systems that provides "analysis and remediation of Section 508 rules and W3C WAI Web Content Accessibility Guidelines, providing efficiencies of over 95% as compared to a manual effort. In addition, RAMP™, written in Java for platform independence, is also accessible to people with disabilities."
"Total Validator is a free one-stop all-in-one validator comprising a HTML validator, an accessibility validator, a spelling validator, a broken links validator, and the ability to take screenshots with different browsers to see what your web pages really look like."
